STOVE-PIP-E-GROOVING MACHINE.

SPECIFICATION forming part of Letters Patent No. 376,173, dated January 10,1888.

7 Application filed June 9, 1887. Serial No. 240,764. (No model.)

To aZZ whom, it may concern.-

Beit known that I, EDWARD G. VVILOOX, a citizen of the United States, residing at Ohicago, in the couuty of Cook and State of Illinois, have invented certain new and useful ImprovementsinStove-Pipe-GroovingMachines, of which the following is a specification, to Wit:

This invention relates to an improvement in Stovepipe-grooving machines; and it consists cured a casting, a, provided with a mandrel,

a", projecting therefrom, such as is commonly used by workmen for the purpose of forming stove-pipe. The upper end of the casting a forms a guide, in which slides a horizontal rod or bar, b, having upon its forward end a fork, in which isjournaled the grooved wheel I), of suitable size for the purpose in view. The fork is extended beyond the wheel, and

there forms a handle, b, by which the wheel has previously been joined together along one side, in the usual manner, is placed upon the mandrel with the seam uppermost, and the grooved wheel isthen drawn over it and pushed back again, the weight being slifficient to press the joint down to proper shape, while the flanges of the groove in the roller at the same time prevent any spreading of the material till it is complete and aid in pressing it into shape. At the forward end of the stroke the momentum of the weighted wheel is g checked and started easily back by the spring, as will be evident at once. Any size of pipe is readily operated upon, and the machine is simple and not liable to get out of order.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is- V 1. In a machine forgrooving stove-pipe, the combination, with a mandrel, of a weighted grooving-wheel' running upon said mandrel and provided with a guide-arm sliding in the heel of the machine, substantially as and for thepurpose set forth.

2. In a stove-pipe-grooving machine, the combination, with the heel frame or casting and its projecting mandrel, of a rod sliding through the heel-casting and provided With a spring upon its rear end and a grooved wheel on its forward end, and ayoke and weight suspended from said-wheel, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

EDWARD G. WVILGOX.
